S11 series 10KV /6KV to 400V dual high voltage oil immersed transformer

It is characterized in that: it includes an even number of series-parallel sections and a number of tap sections, each series-parallel section has the same size, the tap of the series-parallel section is led to the series-parallel switch through the cable, and the tap of the tap section is led to the tap-changer through the cable. In the above, by adjusting the series-parallel switch to connect or connect each series-parallel section in parallel to realize the voltage conversion, by adjusting the tap switch to cut off or connect some of the tap sections, to achieve the purpose of increasing or decreasing the number of turns, to achieve the fine-tuning of the voltage, so that the transformer is in high voltage. , The turn voltage and the output voltage remain constant when running under the two voltages.
